Toner for Brother TN-3520 Black | Premium Class – Maximum Performance XL

Optimize the costs of high-volume printing in your company by demanding uncompromising, corporate quality and perfect readability of each document. The top-class TN-3520 replacement toner (version with maximum capacity XL) is a brand new premium product, fully designed for stable and intensive operation in very fast laser printers and multi-function devices from the Brother HL and MFC series. It guarantees deep, expressive black, excellent sharpness of small fonts and impeccable and uniform coverage of invoices, contracts, reports and barcodes.

The tray is equipped with a modern, factory-installed counting chip of the latest generation, which translates into immediate recognition of the cassette by the Brother device and stable and failure-free monitoring of the amount of remaining dye. The use of spherical, microstructured polymer powder with an optimal melting temperature prevents toner spillage, eliminates the gray background phenomenon and effectively protects the photosensitive drum and advanced mechanical components against premature wear. The product is packed in ecological, neutral cardboard packaging (neutral box), which allows you to eliminate unnecessary marketing costs and offer the highest quality components at an excellent price.

Why choose Premium TN-3520 toner?

• Extreme XL efficiency: The chamber design allows you to print up to 20,000 A4 pages. This drastically reduces the cost of a single print and reduces technical downtime and the replacement of consumables in the office to a minimum.
• Deep, business black: The special pigment formula ensures excellent, high contrast of texts and charts without smearing, fading or contamination on the sheet.
• Reliability at high speeds: Made of 100% solid, brand new components resistant to thermal and mechanical loads, which guarantees smooth operation even during the fastest printing runs.
• Neutral Box: Environmentally safe, economical cardboard packaging that effectively protects the cassette during transport and optimizes the final price of the product.

Packaging information and operating instructions:

The container is protected with an airtight, moisture-proof protective foil and a special air bag placed inside a stiff, neutral cardboard box. This protects the advanced mechanical system and cartridge seals from logistical shocks and exposure to UV light.

Installation tip: Due to the very large capacity of the powder chamber in the TN-3520 model, before installation, it is necessary to remove the cassette from the packaging, remove the plastic covers and orange transport locks, and then, holding the toner horizontally, shake it vigorously 5-6 times from side to side. This treatment perfectly loosens and evenly distributes the micropowder that has settled during storage. This facilitates its correct dosing by the device mechanism, ensuring impeccable black depth and the highest print sharpness from the first page. Finally, remove the entire protective tape (if any) in a smooth motion.
